A distribution waterfall is basically a way to decide who gets paid first and how much in the BMF.io affiliate program. Instead of just giving everyone the same cut, it breaks things down so the top performers or certain affiliates get paid first or get bigger rewards. This makes it fairer and pushes affiliates to work harder since they know their pay depends on how well they do. It also helps the company keep track of payments and avoid overspending. Plus, it keeps things organized when there are lots of affiliates with different deals. In short, distribution waterfalls make paying affiliates simple, fair, and motivate everyone to do their best.
